.ln machines present in use having a parieon, mould which sucks up theglass in the interior of the furnace, the plane of ciosiiug of thismould is turned towards the interior of the furnace; it results fromthis, after the suction, as the joints are practically never tight, hotenter into'the interior of the mould, end due to the direction of theplane of closing, the gases sucked in through the joint situated. on theside of the interior of the furnace are :it o tern nu'uture muchi'iigher then those of the entering tin'ough the joint situated in frontof the opening of the furiiuice,

it follows that the mould is submitted, in two diuinetricully opposedregions, to very dii'l'crcut teznpcinturcs during, the time ofsinzii'on,

Under these coiulitions, the glass sucked up is in contact with wallshaving unequal ijel'lipfiy'iiiLLIQS, that the purison obtained is hotterupon. one port of its lateral surface. The incoruonicncc which resultsfrom this is, Tthat; utter tb" final blowing of the pzirison,

On the contrary, hy the present invention, the two joints are in planeperpendicular it W finishing moulds U, ithc axes of moulds present theirclosing plane turned towards the interior or the furnace.

The machine according lo the invention is, in addition, characterized bythem-range- Inent or the finishing moulds C designed with o view toreceive, in conditions easily carried into effect, the pzu'ison at itsexit from the pair on moulds above specified.

These finishing" moulds C are, as is seen clearly in Fig. 7, situatedlaterally at the level of the parison moulds A,'ut the end of the roartravel of these latter, so to re ceive the purison utter the opening ofthe purison moulds, with a minimum movement oi the said purison.

In addition by this arrangement, the space beneath the purison mouldsremains entirely free, which permits of ventilating easily, under thebest possible conditions, the said parison moulds, when they are broughtto the i'uickward position.

The arrangement-oi? opening of each porison mould permits, in addition,to consiruct a machine comprisin; two purison moulds mounted, the one onone side and the other on the other side of a common support andabreast, so that both of thc n'inay suck up the glass under the someconditions of ternperuture.

It is necessary to note that, due to their method of opening, theobstruction ot these use moulds is reduced to n minimum, andconsequently the openiru;- in the furnace is itseit reduced to emininiun'i.

The two porison mouids which are comprised in the machine are cousitutedeach by two opening shells i and 2 mounted in :1 common siu'iport,likewise opening; in two parts 3 and 4, moving according to thedirection of 2!. siide which passes through them at their centre (seeFigs. ll and 12).

One of the parts 3 of this support {ixcd to the slide 5 to which itconnected by a pivot (5 around which the suid part: 3 can slightlyoscilhiie.

The second part i is lined to the end of two siides 7 and reds noon theslide 5, upon which it can move. i

These siides 5 and '2', wiiicli are adapted to control the opei'iing andclosing of the parison moulds, are carried and guided in supports 8 and9 of a carriage 1e and receive their movement from ecrenked sluift 11 byiii) muse? The connecting rods 12 and 13.2w attached at one end upon theslides 7 and-at the other end upon two similar cranks of understoodthat, during the rotation of the crank shaft 11, the slide on the onepart and the slides'7'on the other part move in opposite directions andthat it half revolution ot'this shaft 11 causes theopcning ot' tll6)2ll'l$ )ll= moulds, whilst the other half revolution causes the closingof some.

These two half revolutions may be nccomplished alternately in one andthe other direction and are controlled, in the example shown, by adouble sector 15 gearing with pinions 16 on the shaft 11 and operated byit vertical slide 1? conveniently guided in the frame or" the machine.This slide 17 receives its motion from a lever 18 pivoted at it) andcarrying two rollers 20 which.

' engage respectively in similar grooves 21 formed in the inner facesot-the plates 22 and 23. (Fig. 3).

The shells Ii and 2 of each parison mould are irovided respectively witha collar 2 simply resting upon a groove'25 formed in each of thesupporting pieces 3 and 4., ns'seen' clearly in Fig. 12. I

By this arrangement the shells 1 end 2 can move freel in theirsupports'and can thus he applie one against the other after the parts 3and have come together, and

thus ensure the proper closing of thesev moulds. This result is all themore easily ned as the pressure transmitted by the sorts irand at to theshells is effected at i. screws 26.

Further, if the two shells 1 and 2 of one parison mould come intocontact with the two other shells of the other perison would, theselatter will nevertheless by applied. one against the other by the factthat lbavpsrt 3 of the support can oscillate slightly around the axis 6which connects this part to the central slide 5- (see Fig. 11).

lhis port 3 of the support thus forms it winging bar which assures, incombiiun tion with the mobility of the shells in their simports, theperfect closing of the two purison moulds, Whatever may be thedifl'crences of size or of dilatation of these moulds.

This arrangement is very important, above all in the case Where theparison moulds take their glass by suction and permits, its will beunderstood, in as perfect o manner as possible, the tightness of thejoint between the shells to he assured.

The parison moulds and the slides5 and l single point of contact, 1neach shell, inexemplercpresented in Fig. 11 by the 6 are mounted, asstated above, in u carriage, which, constituted by two twin bars l'('.l5 at the front and at the back upon two sets of rollers 2? and 28 uponwhich it can be nioved in order to cause the purisou moulds to enter thefurnace and to be withdrawn to the exterior of this latter.

The rear rollers 28 supporting this currige are mounted lixedly, but cunbc recur-- liltflll in height. whilst the forward rollers 52? arecurried by it slide 2!) movable vertically and falling, allot thepenetration of the purison moulds into the furnace, in order;

to cause these hitter to descend until their lower part becomes levelwith the fused glass.

This method of suspension of the carriage Il has the advantage ofgetting rid of much friction and consequently of reducing to the minimumthe power required for moving it.-

Furthcr, the inclination oi the parison moulds caused lit the timcot'the suction of the glass by the lowering of the front rollers 27, may byconsidered practically us nothing by reason of the great distancebetween the said moulds and the rear roller upon which the carriage i0is pivoted.

Preferably, the vertical slide 29 of the front rollers 27 as well as thesupport 30 of the re: r rollers are capable of being regulated in lengthso as to permit of varying at will, the level of the carriage and,consequently, that of the parison moulds.

in the example shown, this slide 29 as well as the support 30 areconstructed, seen in Fig. '3. in the form of sleeves which, screwthreaded internally, slide iif'guides 31, 32 of the frame 33 and areengaged with the screw threaded rods 34 and 35 carrying the worm wheels36 and 37 gearing with the endless screws 38 and 39 the rotation ofwhichonablcs the position of the rollers '27 and 28 to be regulated.

The vertical displacement of the slide 29 of the "front rollers iscontrolled by a lever 40 which, attached to the rod 34, pivots at. ll inthe frame ofthe machine and carries two rollers 42 in Contact. withtwosimilar cums formed upon the plates 2223 so that the ellorts tllctransmitted in e vertical direction.

The control of the movement of lhe curriuge i0 is cfi'ectcd, Fig. 5-. byIii-cons of two levers 45 which pivoting around the axis 15), each carrya roller 47 and are connected to the carriage 10 by rods 48.

The two rollers 47 are engaged in two similar grooves 50 formedrespectively upon the exterior face of the two dics 22 and 23.

Each of the pnrison moulds is surmounted. with o ring mould and asuction head.

These two ring moulds, which are arranged symmetrically with .rcspect tothe longitudinal axis of the machine, are each constituted by two shells51 and 52, resting upon cd lo 21 lever ll urticuliilcd upon an :2i-czirricd by the guidc 9 lined to the coinage 7n) so that the ringmoulds accompany ihis carriage 1.0 and conscqucnn ly, the purisonmoulds, during their inovcincnis 2. l 5 and. 1 3i).

oration of lhe shells 1 and 2 of the corresponding" giarison mould.

The opening of thcsc ring moulds is produced hy a cam 80 acting upon tworollcrs Sl carried by each shell of the ring moulds engaged in a groove93 formed upon theouter face of the disc 9 The same movcment is operatedfor the other cam 8 by 2i symmetrically arranged groove form (1 in theouter face of the disc 160.

As soon as the ring nioulds are open, they are transported into the axisof eochg corre--.

sponding parison mould by the mean s above described and are closed, ashas been explained by the movement towards each other oil the shells 1and 2 of the purison moulds.

When these purison moulds, surmounted by the ring moulds and suctionheads, have sucked up the. glass in the furnace, the cutting on? ofthis; glass, at the base of the parison moulds, is eil'cclii-zd by acutter comprisin two blades 95, which are placed in the same axisiasthat of the parison moulds at the level of their base, and are fixedupon a bar 98 resting at front, and back upon two supporting rollers 97.

This bar 96 rcceivcs a to and fro movement by means of a lcvcr 98 which,in the example represented and for facility of construction, is hingedat 99 upon lever 40 and carries two rollers 100 engaged respectively intwo grooves 101 formed upon the interior faces of the plates :22-23-(Figs. 3 and 4). k

The blades 95 may thus penetrate into the interior of the furnace, slideunder the bases of the parison moulds after they have becn lifted andcut the glass which adhercs t0 the e latter. r

Alter having cfl'ecied this cutting, the blades {)5 close i'hc open baseof the pai'ison moulds and accompany these latter during their returnmovement as far as thcir witlb draivul from the furnace. a

tho end of this return travel, the parison moulds are. as seen inFiner-3, 9 nd 10, above a vertical conduit 102 having a large section,where he cooling'air flows.

These pariso'n moulds in their open positione Fig. 10, or closed Fig.9,,i1re therefore constantly enveloped by a. blast of air during thewhole time that they remain outside the lurnacc.

The two finishing moulds contained in the machine are arranged on eachside of the parison moulds in the same horizontal plane andsymmetrically with respect to the longitudinal axis of the machine, asseen in Figs. 2 and 7.

. These two moulds operate sinmllanwiusly and each of them consists oftwo shells 103, fixed to the end oi levers 101i hinged around axes 105and connected, by links 106, to avertical slide 107 which controlled bya lever 10S turning at 105) and carrying a roller 110 engaged in a camgroove 111 formed for one of the moulds upon the outer face of the plate94 and for the other mould, upon the outer face of the plate 160.

Each slide 107 thus receives an alternate displacement and causes theclosing and opening of each finishing-mould.

A. bottom 112 fixed immovahly closes the base of each finishing mould inthe closed position of these latter.

Thesquare hollow shaft 82, which controls the opening of the ringmoulds, as

above explained, receives in addition, an alternate vertical movementfrom a lever 113 which hinged at 11% in the frame, is pro-, vided with aroller 115 engaged in a cam groove 11 6 of the'plate 9 1- and isconnected ya rod 117 and a lever 15% to the shaft $2 (see Fig. l).

This shaft 82 carries, at its base, a perforated piston 118 (see Fig.;13) suspended by a hollow rod 119 in which',the compressed air can fiowwhich is necessary for the blowing and arriving, by a flexible conduitarranged at the upper end of the saidshaft 82. This compressed air isdistributed by a valve not shown in the drawings.

When the open ring moulds have been displaced laterally away from thecorresponding finishing moulds, and have thus handed to these latter theparison 120 which they were carrying the hollow shafts 821eceive adescending motion until the perforated pistons 118 rest upon the top ofthe parispns, which themselves rest by this ring nponthe top of theclosed finishing moulds, as seen in Fig. 13L

When this operation has been accomplished the air tiows through thepistons 118 in order to blow the pal'isons to their final form.

hen the bottle is finished and the finishing moulds have opened, thisbottle rests upon the fixed. finishing bottom 112 and the 1 top of itsring is at a 'levei above that of the lower part of the carrier for thering moulds.

\Vhen these moulds carry a new parison from the parison moulds to thefinishing moulds, the carrier for the ring moulds encounters the ring ofthe finished bottles and will throw these latter into a. suitableconduit (not represented on the drawing} which will trahsport themoutside the ma chine.

The different mechanical movements nec cssary for the displacements, theopenin the closing of the moulds, the cutting o I, cm, are, as seenabove, controlled by means of the disc cams 22. 523, 9st and 160.

These discs are mounted loosely upon a common shaft 121 around whichthey receive an intermittent rotary motion in such a manncrfthat eachrevolution is divided into six periods during which the following opofthe boring mandrels 72 into the interior of the ring moulds.

The second phase bein icofwmiiioiciii by the action o; progoc u mmovozcoiocs will he pi?ocic.c.- i itiic In effect, the oioppiz'ag teriorof the furnace in order to operate the cutting'otl. Then simultaneouslythe parison moulds and the cutters leave the furnace and come back totheir respective starting points, Fig. 9. There is then produced a newstopping of the cam discs caused, as it has been explained above, at thetime of the proceeding stop andkluring which there is ell'ected thefourth phase of the manufacture. that is to say, the cooling of theglass in the parison moulds.

It is necessary. in eti'ect, in order that a parison may be blown undergood conditions in the finishing mould, that this parison be brought toa determined teniperature which will give to it the desired physicalqualities. It is equally evident that, notwithstanding the artificialcooling, a certain time is necessary in order to assure the cooling ofthe parison. Likewise, as for the suction, this time depends upon thecomposition and the temperature of theglass which is gathered, as wellas the weight of the parison. It depends also upon the form of theparison.

in recapitulation, each element acts more or less during the wholeperiod necessary for cooling, a period which must necessarily varywhenthe object to he manufactured is changed. Also, for the first phase,the projection lll oi: the disc 1%, which will cause the stoppage tocease, will have been placed in a position which is suit-able in orderto give to this stopping the desired period.

When this stop has acted, a new clutching of the corn discs takes placewhich produces a series of movements which constitute' the titth phaseand permits arrival at the siath phase, that is to say, at the coolingof the parison moulds, Fig. 10; these movements are:

l.Simultaneous opening of the parison and finishing moulds. At thismoment the machine has the following aspect:

The parisons liberated from the parison moulds rest suspended from thering moulds, the bottles which have been previously blown are liberatedfrom the finishing moulds and. rest upon the respective bottoms of themoulds.

2.-The ring moulds, carrying with them the perisons, are trensportedlaterally and 3 in opposite directions towards the respective finishingmoulds. in this inovement,-th.e blown bottles are thrown h the ringmoulds and expelled from the machine.

3.-'llhe finishing moulds close around the perils-ans snapsndetljeom thering moulds;

the opening of the ringmpl lds.

The parisons suspendedfrom these ring moulds are liberated and the ringsof these parisons repose upon the upper parts of the finishing moulds 1nthe interior ofwhich the parisons are then suspended, 13).

5.-The ring moulds return to their first position, that is to say, intothe centre of the parison moulds which have remained open.

6.-The square shafts 82 descend until the pistons 118 bear upon theupper parts of the rings of the tiions restl their rings upon thefinishing moulds, (Fig. 13).

5.-'lhe. blowing of the parisons takes place while the cam discs arestopped, in

the manner already explained, so that the sixth phase of the operationis efi'ected.

At-this moment the machine presents the following aspect, Fig. 10; theparison moulds are open above the cooling conduit. 102 and are envelopedinteriorly and exteriorly with the blast of air which circu lates frombelow upwards. 'These arisen moulds have attained, due to the. act oftheir penetration into the furnace and due to the fact of contact withthe glass which the v contain, a relatively high temperature whichrequires to be considerably lowered in order that these moulds canpenetrate afresh into the furnace and again suck up the charges 'ofglass.

In order to lower this temperature, a certain time is required whichdepends u on the quantity of glass carried, the time uring which thisglass has rested-in contact with the walls of the moulds, the mass ofthese mounds, etc. It is in reality upon this factor which depends aboveall the output of the machine, for the period of cooling of the parisonmoulds constitutes the longest of the six phases of manufacture. Theduration of this time is reduced to the minimum, by means of 'theposition given upon the disc 144 tothefprojection which causes afreshthe clutchingoi the cam discs.

If the 'rtifical cooling takes place intlle best osslhe conditions, theparison moulds will be the minimum. For this reason the parison mouldsremain open above, the cooling conduit 102 during the whole period ofstoppage.

When the projection 143 of the disc 144, which limits this stoppage,acts afresh, the movements will recommence in order to repeat the phaseswhich have just been described.

In consequence, after the reclut'ching of the. cam discs, the followingmovements will be produced: I

1.Closing of the parison moulds causing the closing of the ring moulds.

2.,-The slide of the moving part 10 moved towards the furnace.
